I don't understand why you say "*But* the El Torito...". I don't see 
a difference with what the mkisofs manual says.

Where I see some kind of source for potential confusion (at least for 
some users) is (quoting Thomas, but he is not the source of the 
potential confusion):
"This program expects to find the UEFI image as second boot image and 
the Mac image as third boot image. Both with Platform Id 0xef."

My understanding is that:
 0=x86 , 1=PowerPC , 2=Mac 
are all non-EFI systems, which leaves "0xef" for "every" (U)EFI 
system, whether such (U)EFI system is EFI 1.0, UEFI 2.x, a Mac-EFI 
system, or some mix/non-standard firmware.

So, users should be more specific (or clear) when they refer to a 
"Mac" system, as the firmware could be non-EFI, or (some variant of) 
(U)EFI.

Just as a remainder, "-eltorito-platform 0xEF" is equivalent to 
"-eltorito-platform efi" in mkisofs.

I would also suggest, at least **for test(s)**, to use the latest 
mkisofs (ATM, 3.01a24), and perhaps mixing it with Syslinux 
6.03-pre19 (or newer). Although... The scripts/receipts for using 
Syslinux 6.xx in Slackware would need changes, and I am certainly 
_not_ suggesting to actually update Slackware to use Syslinux 6.xx.

Ady.
